ACN 009 067 476 ASX RELEASE 3 June 2011 NEW ZINC/LEAD/COPPER ANOMALY DELINEATED NE OF KIHABE DEPOSIT The Company is pleased to announce that detailed soil geochemical sampling along strike from and 4km to the NE of the Kihabe Zn/Pb/Ag deposit in Western Ngamiland, NW Botswana, has delineated a significant Zn/Pb/Cu anomaly. The new "Lebala" anomaly (see diagrams attached) covers an area of around 10 hectares, discretely defined with soil geochemical sample grades of up to 260 ppm Zn, 260 ppm Pb and 58 ppm Cu. Normal background values for Zn, Pb and Cu in this area are around 10 ppm to 20 ppm. Since the acquisition of a XRF machine in February this year, the Company has analysed around 6,500 soil geochemical samples. These were taken from six prospective target areas within the neo-proterozoic belt which spans the border between Namibia and Botswana. All six targets have generated significant soil geochemical anomalies as follows: Botswana Wanchu - (Zn/Pb) 1.2km long anomaly Tswee Tswee - (Zn/Pb) 55 hectare anomaly Target 52 - (Zn/Pb) 4km long anomaly Lebala - (Zn/Pb/Cu) 10 hectare anomaly Copper - (Cu/Co) 2.4km long anomaly Namibia Makuri Vlei - (Cu/Co) 1.1km long anomaly Whilst drilling is required to delineate resources from these anomalies the Company believes they show good potential to add to the 25 million tonne 3% Zn/Pb resource base of this project area. See Resource Statement attached.
The Company is continuing with soil geochemical sampling over several other prospective areas within its 100% owned 3,000 sq km neo-proterozoic belt. Soil samples are collected from 10cm below surface at sample locations 100m apart N/S and E/W. Samples are sieved down to 0.18mm to collect about 60gm per sample and then stored in standard geochemical soil sampling paper envelopes. Samples are then analysed with an XRF machine, under controlled conditions at the Company s exploration camp. The information in this release that relates to exploration results, together with any related assessments and interpretations, is based on information approved for release by Mr. Giles Rodney Dale of GR Dale and Associates. Mr. Dale is a Fellow of the Australian Institute of Mining and Metallurgy. Mr. Dale has sufficient experience which is relevant to the style of mineralisation under consideration and to the activity which he has undertaken to qualify as a Competent Person as defined in the 2004 Edition of the Australasian Code for Reporting of Mineral Resources and Ore Reserves. Mr. Dale consents to the inclusion in this release of matters based on this information in the form and context to which it appears. About Mount Burgess Mining N.L. Mount Burgess Mining N.L. is an established and experienced Australian exploration company with interests focused in southern Africa. The Company s primary asset is the zinc, lead and silver resource currently being developed at Kihabe-Nxuu in North Western Botswana. The Company has tenements covering the entire proterozoic meta-sedimentary belt between Botswana and Namibia. The area has excellent potential for hosting Kimberlites, rare earth elements and base metals, the focus for continuing exploration. Perth based Mount Burgess has been listed on the Australian Stock Exchange since 1985 and has local asset status in Botswana.
Only soil sampling results above XRF level of detection are shown.
